Field notes / real systems
Practical guides for connecting AI tools to PostgreSQL, MySQL, and OpenAPI through hosted MCP links.
Build and verify PostgreSQL row-level security for AI agents with non-owner roles, FORCE RLS, explicit policies, controlled writes, and denial tests.
Compare Codex Memories, AGENTS.md, task history, and hosted MCP memory. Share persistent project context across Codex, Cursor, Claude Code, and more.
Compare Cursor Memories, Rules, Memory Bank files, and hosted MCP memory. Share persistent project context across Cursor, Codex, Claude Code, and more.
Learn what AI agent memory is, how an MCP memory server supports handoffs between chats, and where structured project memory fits in a real workflow.
Compare Claude Code memory, CLAUDE.md, auto memory, Claude's native memory, and a shared MCP memory server for persistent context across AI tools.
Learn what a Memory Bank MCP server does, how file-based memory differs from structured hosted Agent Memory, and which model fits your AI workflow.
Learn how multi-agent memory works, when agents should share context, how MCP supports handoffs, and which consistency and access-control problems matter.
Create a restricted PostgreSQL role for AI tools with table grants, default privileges, optional row security, timeouts, and denial tests.
Compare @benborla29/mcp-server-mysql, the Python mysql-mcp-server, DBHub, and hosted datamcp by deployment, permissions, credentials, and best use.
Connect Cursor to MySQL through a hosted MCP server. Create a restricted user, configure mcp.json, verify schema access, and test denied writes.
Compare GitHub, Context7, Playwright, Figma, database, and hosted MCP servers using official sources, deployment, permissions, security, and current status.
Compare CrystalDBA Postgres MCP Pro, DBHub, pgEdge, Supabase, Neon, datamcp, and the deprecated official server by deployment, permissions, and use case.
Learn how to build an MCP server: define tools, choose local or remote transport, add auth and tests, then compare custom code with OpenAPI conversion.
Add a remote MCP server to ChatGPT through Developer mode. Covers apps, HTTPS endpoints, OAuth, permissions, testing, refreshes, and common errors.
Add MCP servers to Claude Code with the CLI or .mcp.json. Covers HTTP and stdio, local/project/user scopes, OAuth, API keys, testing, and fixes.
Connect Claude Code to PostgreSQL through a local or remote MCP server. Includes scopes, read-only roles, datamcp setup, testing, and fixes.
Connect Claude Desktop or Claude on the web to PostgreSQL through MCP, with a separate Claude Code path, permissions, OAuth, testing, and troubleshooting.
Connect Cursor to PostgreSQL through a hosted MCP link. Configure mcp.json, start read-only, verify schema tools, and test database access.
Yes, ChatGPT can connect to PostgreSQL through a remote MCP app. Follow the current OAuth, permission, testing, and troubleshooting steps.
Connect Supabase to Cursor with the official MCP server or a database-focused PostgreSQL link. Compare both paths and configure scoped access.
Set up an MCP server in Cursor with project .cursor/mcp.json or global ~/.cursor/mcp.json. Copy local and remote examples, verify tools, and fix errors.
Learn how database MCP servers expose schema and query tools to AI clients. Compare local, provider, self-hosted, and managed options safely.
Turn a FastAPI OpenAPI schema into a hosted MCP server. Connect /openapi.json, configure API auth, restrict methods, and test the MCP link.
Make a REST API read-only for AI agents with method filtering, endpoint visibility, least-privilege credentials, rate limits, approvals, and audit logs.
Learn how MCP authentication works with OAuth 2.1 and API keys, how authorization differs, and how to enforce scopes, permissions, and revocation.
Build an MCP governance program with server inventory, ownership, approval, least privilege, change control, monitoring, revocation, and incident response.
Build useful MCP logs without leaking secrets. Learn the event schema, correlation fields, denied-call tracking, retention, alerts, and incident workflow.
The official PostgreSQL MCP package is deprecated and archived. Verify its status, compare maintained replacements, and preserve read-only protections while migrating.
Turn a NestJS Swagger API into a hosted MCP server through OpenAPI, or choose native MCP for custom tools, resources, prompts, and workflows.
Compare OpenAPI-to-MCP conversion with a custom MCP server across tool design, authentication, workflows, hosting, maintenance, security, and cost.
Add MCP servers to VS Code through the gallery, Command Palette, or .vscode/mcp.json. Covers HTTP, stdio, OAuth, secure inputs, testing, and fixes.
Connect a Neon PostgreSQL branch to Claude and Cursor through a hosted MCP endpoint with a restricted role, verified TLS, and read-only access.
Compare hosted, self-hosted, and local MCP servers by security, credentials, cost, maintenance, team access, and operational ownership.
MCP security guide covering common risks, OAuth, token handling, least privilege, prompt injection, audit logs, revocation, and a production checklist.
Secure OpenAPI-to-MCP access by separating client authentication from upstream API credentials, with practical API key, Bearer, Basic, and OAuth guidance.
Turn an OpenAPI 3.x or Swagger documentation URL into a hosted remote MCP endpoint. Configure auth, read-only access, and test real API calls.
An MCP server exposes tools; an MCP gateway controls access to them. Compare architecture, authentication, permissions, credentials, audit, and use cases.
